How should our hands be positioned in prayer? Is there a right or wrong way?
Various biblical passages seem to indicate that raising the handpalms is an appropriate gesture for prayer. Verses like kohelet 4:5 seem to state that the folding of the hands is for fools, yet in Shabbat 10a it says that Rava in his prayer would remove his cloak and clasp his hands and pray. He said that he would do so as a slave before his master, who appears before him with extreme submission.
Does the Tenach show us a way how to pray with our hands? (Although Rabbi Heschel seemed to have prayed with his feet at least once, I’m sticking to the hands and not the gesture of other body parts).
